The system software is designed according to the module, mainly including system initialization module, key processing module, relay array control module, data processing module, display printing module and automatic shift test module.
1 main program: by calling the system initialization program, etc., to achieve the purpose of testing. The flow chart is shown in Figure 1.
2 Relay array control module: According to the test requirements, the control of the relay is realized, and the detection point is connected to the Rx measuring end. The process is shown in Figure 2. 
3 automatic shift test module: This module completes the task of high and low resistance shifting, turning on the programmable amplifier and collecting data. The flow chart is shown in Figure 3. 
Due to space limitations, other block diagrams are omitted.
The method described in this section has been adopted by the integrated detection system, which realizes the automatic detection of insulation resistance between multiple contacts, and the measurement accuracy has reached the index mentioned in the paper.
This method is also applicable to the automatic detection of insulation resistance of other electronic devices.
As a chip design and produce company, completely design process and independent core technology. The core technology include algorithm,fine optimization of integrated circuit micro-structure ,low power technology, advanced chip packaging technology system level power and cooling technology. These core technologies and engineering methods have been successfully validated and applied in the mass production of our block chain server chips and products.
